Abstract:
A method and apparatus for interconnecting circuit board assemblies using memory metal wires mechanically inserted into through-plated holes. The invention has its application in the interconnection of stacked circuit board assemblies where kinked memory metal wires are stretched so the wires are substantially straight; inserted into axially aligned through-plated holes of circuit boards; and released so that the memory metal wires reform their original kinked shaped within the through-plated holes, forming an electrical connection between the circuit boards. Memory metal alloys are used in the construction of the kinked memory metal wires to take advantage of the pseudoelastic behavior of the alloys in the austenitic phase below the forming temperature range.
Abstract:
A method and apparatus for interconnecting electronic circuits (104) using nearly pure soft annealed gold mechanically compressed within through-plated holes (111). The invention has its application in attaching integrated circuit dice (104) directly to circuit boards (110) by ball bonding gold wires (101) to the bonding pads (105) of the integrated circuit dice (104) in a substantially perpendicular relationship to the surfaces of the dice (104) and inserting the gold leads (101) into through-plated holes (111) of circuit boards (110) which provide an electrical and a mechanical connection once the leads (101) are compressed within the through-plated holes (111). The present invention also finds its application in the interconnection of sandwiched circuit board assemblies (200) where soft gold lead wires are inserted into axially aligned through-plated holes of the circuit boards (212, 214, 216, 217, 219, 221) and compressed so that the gold lead wires compress and buckle within the through-plated holes, forming an electrical connection between the circuit boards (212, 214, 216, 217, 219, 221).
Abstract in simplified Chinese:供电子模件或相似物用之改良式连接器,此连接器含一外壳,其有一管座开口其大小及形状适于接纳一电子模块,及许多端点装在外壳上。每一端点有一底部具有一层非焊接材料涂层在底部之一侧以防焊锡将该侧黏住。当端点安装在一导体垫上俾焊剂可由细管巢在毛细作用力影响下自具有非焊接材料层之端点之一侧流向另一侧以形成在另一侧上之焊接点时,在底部份之下面管道表面形成一细管巢。在端点之中部四周涂层一非焊接材料环以防止焊剂流向位于环上面之电接触表面。结果,连接器端点可利用简单而经济方式焊接在印刷电路板上而不会形成焊接缺点。
